Subject: (fractint) Another Paul Carlson Formula
Lo Group,
Taking the priviledge to post the formula and some of the pars which Paul
shared with us on the chat channel, plus a few of my own pars for it. The
comments are his, and it really is a fun formula. The Newbies out there
will find that this formula is easy to use and will give some quick results.
Enjoy
Earl Simpson

This formula has no special mathematical significance - it's
just fun to play with.

Subject: Re: (fractint) Another Paul Carlson Formula
Earl,
Thanks for posting the formula that I distributed during
the chat last night. Thanks also for the additional
excellent pars! espc0002 is my favorite, but they're all
great. espc0004 is missing the map file, but I used the
cyan-red colormap which looked very nice with it.
I think the file that I sent you must have gotten truncated
because the ending curly bracket is missing from my fourth
par and my fifth and sixth pars are also gone in your posting
so I'm sending the whole thing here.

Very nice Paul!!!!!
Here is a quick zoom on your first par that somehow reminds me of lotus blossoms

Thank you Damien!!!!!!!!!!
And good suggestion Tim.......but where to put what???
The number of pars posted has certainly increased dramatically......I was
looking at Les' site.....there were just 50 or so pars posted last September.
But for me getting the frm's and checking out everyone's pars is enormously
helpful. Just as helpful as questions about Fractint itself. And I have one for
the list. REady?????
On what basis do you folks choose the among the calculation methods available in
the basic options?? I recall you all said g doesn't always bring out the true
intentions of the artist. But why chose t over....say 2?

The thing is, my wife left at 4:30 AM this morning on

my computer was sitting there looking lonesome, so I've
been keeping it company since then, for the past 11 hours.

Subject: (fractint) raytracing and fractint
Hello!
I'm quite a new user and some days ago I discovered, that Fractint can
output a file for raytracing program. I read a help file about that
and decided to get a Pov-Ray program (I spent a lot of time
downloading it from internet - the setup file "weights" 4 megs!). In
Fractint's help file is written that a raw2pov file converter is
included in setup file (or something like that), but I can't found it
anywhere. So I tried to download it from internet. Bad luck - now I've
got three or four converters and none of it is working properly. If
you have a raw2pov converter or even know where to get it, please
mail_me. Thanks!
Andrej
P.S.:Just one more request: My age is 14 and I'm still learning
English, so, please, tell me if something is written wrong.

Wow! You wizzled that one real good - beautiful! It sure does have

Note to others: Wizzle's par does not go with the subject formula,
it goes with the one Earl posted.

First of all I would like to say that I am new to this list, but I am having
a lot of fun checking out everybodys fractals. I've been playing around with
Fractint since version 16 or so. My first fractal was the classic Mandelbrot
generated on a 286, using a program written in Pascal. It took over an hour
to generate! Boy do I love today's faster machines, and better programs.
I don't know about others but for me, I prefer to use boundary. I enjoy
watching the fractal being generated almost as much as seeing the final
product. Tesseract is almost as much fun to watch.
Below is a little thing I have being playing with. I got the map from
somebody's web page, but I don't know who it was. I just love the metallic
colors. :)

Subject: (fractint) 3Way Gedeon's Euler Formula
Okay, I broke my promise. It's been 13 hours now
and my wife is still out chasing birds. Their goal
was 100 species in one day and they're probably on the
other side of Colorado stuck on number 99. Anyhow,
I've started playing with Gedeon's excellent Euler
fomulas and pars and here's a couple of results.
They execute very quickly.
comment {
This formula applies my 3Way rendering method to the
first of Gedeon's Euler formulas. The two pars are
zooms into two of Gedeons pars, gp-eul01-06 and
gpeul01-09. Try color-cycling the first image.

Subject: (fractint) Similar attitudes -- fourth attempt
I've been trying to get this letter posted all afternoon,
with no success. If this attempt fails, I'll consider the
letter jinxed. It's a little bit outdated now anyway.

The "Fractal-Art" list has been saved by Damien Jones. So go
ahead and subscribe. The traffic on the list is much less than
on the Fractint list, and every day in my FOTD I have a few
words to say about things such as fractals, the fourth
dimension, quantum mechanics and the nature of existence, etc.
And you won't believe the fractal adventures of Jay Hill's
Doctor J. and his blushing bride, Doctor E.

I thought you had read *my* past posts and were quoting me.
Apparently we feel the same about fractals. I don't try to
create great works of fractal art, nor do I try to reach new
levels of mathematical cleverness; I simply enjoy exploring the
abstract yet strangely real world of fractals.
I too prefer short, simple formulas and inside=0. I keep my
use of skewing, stretching and rotating, as well as the fancy
outside and inside coloring options, to a minimum. IMO, there
is only one supreme fractal -- the four-dimensional figure
known as the Z^2+C Julibrot, which includes as sub-sets the
classic Mandelbrot set, all the perturbed Mandelbrot sets and
all the Julia sets. The things I do to the Julibrot shouldn't
be done to a dog.
In addition to exploring the Mandelbrot and Julia sets, I
frequently explore the four other perpendicular families of
sets that the Z^2+C formula can create. I have named these
four other families of sets, "Oblate Sets", "Parabolic Sets",
Rectangular Sets, and "Elliptic Sets". (Today's FOTD will be
a Rectangular set image.) I also frequently explore the
oblique slices of the Julibrot.

There will be no Frac-Trek list, because Fractal-Art is not
going down the drain.

Not for some considerable time yet, I presume. Fractint is a
great fractal program, but it is not the only fractal program.
The number of fractal-related lists as well as fractal programs
can only grow in the next several years. There are many
specialized applications of fractals that could support a
mailing list. And as the internet grows, all specialty lists
will become more viable.
That's it for now. I'll check your just-posted frms and pars,
and give my report. See you in fractal land.
